With the Greenwich High Music Hall now estimated to cost $42 million and still climbing, people are rethinking the project. There’s talk of eliminating the orchestra pit, reusing an older portion, and on and on. The end result, it seems to me, will be a dog’s breakfast of old, new and make-do, all so the proponents can claim they built something. That’s a dumb reason to spend what’s probably going to be fifty-million bucks, if we’ll end up with the same inadequacies we’ve been muddling along with these past decades. I say, punt.
